LOCK.

Application led May 23,

To all whom t may concern.'

Be it known that I, ISAAC J. SEGAL, of Malden, in the county ofMiddlesex and State of Massachusetts, a citizen of 'the' United States,have invented a new and useful Improvement in Locks, of which thefollowing is a full, clear, and exact description,

reference being had to the acceompanying drawings, forming a part ofthis specication in explaining its nature.

The invention relates to an improvement in locks and essentially to a.coin-controlled lock.

lt is among the objects of the invention to provide a coin-controlledlock permitting of the following operations: retraction ofthe bolt ofthe lock from the exterior side theren of by the turning of a knob orhandle upon the insertion of a coin which assists in affecting suchretraction; by an independent x'nechanism effecting retraction of thebolt from the rear side of the look on turning a knob or handle;preventing retraction of the bolt by the turning of either knob orhandle from the front or back of the lock and permitting retraction ofthe bolt under all circumstances from the outer side of the lock by akey-controlled mechanism; preventing the admission of a coin to the op'erating parts of the lock after a coin has once been inserted and beforethe release of such coin, all of which operations are found to be verydesirable in a lock of the present type.

A further object is to provide the lockV with a counter capable ofautomatically registering successive uses of the lock under conditionswhere a. coin is employed for as'- sisting in the retraction of thebolt. A

In a lock having the aforesaid adaptability it is my further object toprovide conoise intimately associated or combined mechanisms possessingfew wearing parts and any of which parts are easily replaceable;mechanisms, also, that are operable Iunder all conditions of use andwhich are `practically fool-proof. In other words, it is my object toprovide a coins-controlled Vloc-k of great flexibility especiallylfitted vto perform the purpose or purposes for which it is designed.

T he invention can best be seen and understood by reference to thedrawings in which- Figures l and 2 show in side elevation the interiorof the lock casing and various of the 1.921. Serial No. 471,630.

Fig. 2 showing the parts in a different op erative position from thatshown in Fig. 1, alllof which will later be referred to in detai Fig. 3is a section on line 3 3 of Fig. l(

Fig. 4 is avsection on line 4 4 of Fig. 1.

Fig. 5 is an inside elevationof the lock casing, the interior mechanismbeing covered and held in place by a plate carrying the countingmechanism or register later to be referred to. s

Fig. 6 is an elevation of the interior of the cover of the casing, and

Fig. 7 shows partly in cross section and partly in plan a detail ofconstruction to which reference will later be made.

The operating parts of the lock are contained within a casing 1 having acover 2. The casing has a back la, side edge plates 1b, le,respectively, a top edge plate 1d and a bottom edge plate 1e. The coveris provided with interior posts 3 by which it is: secured to the casingby screws 4: entering from the back. The casing contains a. plate 5which assists in retaining and carrying various of the operating parts.This plate rests upon the ends of posts 6 projecting from the back ofthe casing and to which the plate is fastened by screws 7 8 representsthe head of the bolt and 9 its shank. The bolt operates through anopening l0 in the side edge plate lb of the casing and from this edgethe head protrudes when the head is in engagement with its keeper (notshown). The shank 94 of the bolt is slidable on the back of the casingand is provided with an end crossbar 10 which engages the interior ofthe side edge plate 1c of the casing when the bolt is occupying aretracted position for defining` such position. rIhe shank is bifurcatedand into the slot 11 thus left extends a short pin or stud 12 from theback of the casing, acting to assist in guiding theshank during` thesliding of the bolt. The shank ofthe bolt is also guided on the lower orunder side by fixed guides 13 and above by the lower end of a coin chute15 fixed to the casing, and to which special reference will later bemade. The shank of the bolt is also provided with a flange 16 whichengages the interior of the side edge plate 1b of the casing when thebolt is occupying its extended or engaging position for defining suchposition.

The I bolt is yieldingly maintained in a normal engaging or extendedposition by a spring 17.

rfhe bolt is initially controlled by means of a key-controlled lock. Forthis purpose a lock 19, preferably of the pin type, is arranged withinthe cover 2 of the casing adjacent the shank of the bolt. r1`he barrel Qof the lock 19, turned by a key, is provided with an arm 21 whichengages an arm 29, on the shank of the bolt, which extends through aslot in plate 5, the relation of the parts being such that the bolt maybe retracted upon turning the key in the lock 19 by the engagement ofthe arm 21 with the arm 22 on the shank of the bolt. The bolt may bethrown into a disengaging position by the key-controlled lock justreferred to irrespective of the other operative parts later to bereferred to.

Reference will now be made to the mechanism by which the bolt may bethrown into a retracted or disengaging position uponthe insertion of acoin. 1t will irst be observed that the top edge plate 1d of the casingis provided with a slot 24 through which a coin may be inserted.immediately below this slot is arranged the coin chute member 15,previously referred to, fixed to the casing. The face of this chutemember is flush with the inner side of the slot 2/1 and also with theouter side or face of the shank of the bolt so that a coin insertedthrough the slot 24 maypass downwardly over the face of the chute memberand over the shank of the bolt. rlhe chute member is provided with sideedge flanges 25., 26, respectively, the flange 26 being' provided withal lateral extension 27. The flanges 25, 26 and eX- tension 27 riseabove the face of the chute member 15 a distance about equal to thewidth of the coin and provide in part a bearing for a plate 29 forming`a chute member opposite the member 15 and between which members the coinis directed to pass downwardly over the shank of the bolt as aforesaid.

The chute member 29 consists of the head and body portion of a slidemember 30. This member rests and is slidable upon the sides 25, 26 ofthe coin chute and the extension 27 therefrom. The body of the inemberextends downwardly over the outer face kot the shank of the main boltand is spaced therefrom to admit of the downward passage of aI coin outof the chute over the outer face of the shank and between it and themember 30. Vvvhen the member is ocrupying its normal position the rearedge 31 thereof lies forward of the plate 10 on the rear end of the boltshank. Gn its forward side in the direction of the head of the bolt themember is provided with an arm extension 32 which rests against and isslidable upon another slidable member 33 later to be referred to. At itslower end the member is provided with an inwardly and downwardlyprojecting foot 34. Projecting` from this foot and extending therefromin the general direction of the head of the bolt is a bar extension 35which slides upon the back of the casing and between the guides 13 and aguide 36 iiXed to the casing. rllhe normal position of the member 30 isdefined by the engagement of the edge 37 of the head 29 of the memberwith one of the posts 6 of the casino; and in which normal position themember 30 is yieldingly maintained by the bearing of a spring 38.

1n connection with the member 30 attention is directed to an edge 39with which this member is provided. This edge lies at the junctionL ofthe foot 34rwith the member and faces the passageway through which thecoin drops from the coin chute downwardly over the outer face of theshank of the bolt. As will later be eX- plained, the coin engages thisedge during its downward passage, the edge assisting in the retentionot' the coin until its release.

rlhe slidable member 33 is arranged forward of the member 30 in thedirection of tbe head of the bolt and is slidable over the shank of thebolt and the bar extension rllhe member 33 is provided on the inner sidethereof with an elongated stud 40 which tits within the slot formed inthe bifurcated shank of the main bolt and guided therebyn The member 33is also guided during its sliding movement by the guide 3G` the memberbeing provided with a flanged edge l1 in engager/nent with this guide.rlhe portion l2 of the member 33 is the portion over which the arm 32 ofthe member 30 extends as explained above, and this pirtion of the member33 is madeof just suflicient thickness to assist in provid ing forproper sjnacing of the member 30 in relation to the shank of the bolt toadmit of the passage of the coin. The portion 43 of member 33 is alsomade of the same relative thickness as the part 4t2 in order that as themember is moved backward it may slide beneath the lower portion of themember 30. Attention is also directed to the rear edge 1114i of themember 33 which faces the openingor slot throng-h which the coin ispassing, this edge being complementary to the edge 39 on the member 30and assists in the retention of the coin during` its downward passage,in other words. the coin contacting with the edges 39 and le and beinginitially retained by them. Attention is also directed to "the curvatureof the edge 11i which is for purpose new kto be referred to.

The member is retained to occupy a normally defined position from whichposition the member is slidable in the general direction of the rea-redge of the Casing.

loo

It is when occupying its normal defined position that the coin willcontact with the edges 39 and 44 as aforesaid, the coin initiallycontacting with the lower portion of the edge 44 as shown in Fig. l. Asthe member 33 is moved backward the coin owing to the curvature of theedge 44, will be thrown upwardly and occupy a position substantially asshown in Fig. 2 where the coin is shown lifted out of contact with theedge 39 of the member 30 and into contact with piece 45 loosely arrangedon the rear end of the bolt shank and retained by the plate 10 on theend of the shank. As the movement of the member 33 is continued it will,through the interposition of the coin and piece 45, act upon the end barl0 on the bolt shank and thereby7 move the bolt when the bar l0 willcontact with the rear edge plate 1c of the casing, which defines theretracted position of the bolt.

The member 33 is positioned and its movement controlled by mechanismconnecting with the front or main knob of the lock or 'door to which thelock is secured, and it is accordingly by turning this knob after theinsertion of a coin that the bolt -may be moved into its retractedposition.

Referring to such positioning and controlling mechanism, 46 representsthe knob on the front side of the lock and accordingly on the outer sideof the door to which the lock is secured. The knob is arranged to turnwithin a socket 47 on the cover 2 of the casing. The knob carries ashank 48 which fits into and is secured to a hub 49 socketed to turnbetween the back of the casing and the plate 5. The hub carries an arm50 which connects with the sliding member 33 by a stud 51 on said membercontained within a slot 52 in the end of the arm. The arm 50 isyieldingly held to bear against a post 53- on the casing by a spring 54and when occupying this position the arm acts to hold the member 33 inits initial operative position above referred to for holding the coin.On turning the knob the arm and member 33 with it will be moved backthereby retracting the bolt through the interposed coin and piece 45 asexplained above. On the release of the knob the arm and member 33 willbe returned to their original positions by the spring 54 and the boltwill be moved back to its engaging position by the spring 17. Theoperation does not effect a release of the coin, the coin thencontinuing to rest on the lower end of the edge 44 of tha-member 33 andedge 39 of member 30.

Reference will now be made to the means by which the bolt may beretracted and the coin released. This is accomplished by mechanismoperated from the inner side of the door to which the lock is securedand comprising a knob 56 having a shank 57 which extends 'through theback ofthe casing and fits within a hub 57 socketed to turn between said.ba-ck and the plate 5. The hub 57 carries an arm 58 which extendsupwardly to bear against the front side of the foot 34 of the slidablemember 30, the lever being maintained in this position by means of anarm 59 on the hub 57 which bears against the interior of the side edgeplate lc of the casing. Vhen the knob 56 is turned the arm 53 will beactuated to retract the member 30 which, by its engagement with the endpiece 10 on the rear of the bolt shank, will move the bolt into aretracted position. Tnasnxuch as the member 30 is retracted during thisoperation and as this is one of the members acting to hold the coin, thecoin will accordingly be released to drop into the bottom of the casing.

Another phase of the lock resides in a mechanism for preventing theretraction of the bolt by turning either of the handles 46 or 56. Thisoperation is initially effected by mechanism operable from the innerside of the lock or door to which the lock is secured and comprises athumb piece 60` having shank 61 litting within a hub 62 socketed to turnin. the back of theV casing. The hub 62 carries a linger 63. This fingeris in operative engagement with a latch 64, the finger being containedwithin a socket 65 in the side of the latch. The latch is guided by aheaded pin or screw 676 fixed to the casing back, the shank of the screwextending through an elongated slot 67 in the latch. At its upper endthe latch is provided with a tongue 68which lies normally within anopening formed through the guide 36. The forward side edge Vof the latchis provided with an arm 69. Aflixed to the latch is a spring 7 0 whichbears against a fixed stud 70 on the casing. The latch has in it bendsor indentations 702, 703 into which the stud fits as the spring is movedto run over the side of the stud and by which means the latch isyieldingly held in the engaging or disengaging position to which it maybe moved. The latch occupies normally a retracted position. as shown inFig. l. Assuming the bolt to be extended or in its engaging position.the turning of the button Y60 operates to turn the finger 63 and therebythrough the finger elevate the latch. Thereupon the tongue 68 will passthrough a slot 7l formed in the under side of the slide bar 35 securedto the sliding member 30 as aforesaid. The sliding member 30 cannot thenbe moved for retracting the bolt on turning the knob 56.

The engaging position of the latch will also bring the arm 69 on theside thereof into line with a stud 72 on the under side of the lever 50,thereby preventing this lever being thrown backward for retracting thelli) lill

bolt on turning` the knob a6. @n moving` the latch baclr to its originalposition upon turning the thumb piece release Will be etfected to permitretraction ot the bolt by turning either ot the lrnobs lo or 56.

Further provision is made in the construction of the look whereby theslot may be closed after a coin has onoe been inserted and the boltmoved into a retracted position. ils previously explained7 the initialretraction ot' the bolt is obtained by turning` the lrnob fil-6 whichacts through the lever 5G to retract the member 33. As the member 33 isretracted, the coin, initially resting on the ,members 33 and 30, isliil'fted into Contact With the piece 45 on the shank oi toe bolt7 whoreupon as the retraction ot the member 83 .is continued it, through theinterposition ot the coin and piece l bearing' against the bar on theend of the shank, effects a retraction of the bolt. rlhe piece thusYlormingf one of the operating parts is a piece loosely arranged uponthe rear end ot the shank of the bolt and is held in place by a stud 74lined to the member and extending through the slot 11 in the boltshanlr, the stud being` secured on the under site by erosslt-ar 7 Whenthe bolt is extended and the parts are occupying their initial operativeposition permitting' of the insertion or' a coin, the crossbar 75 on theunder side ot the piece el* will have engagement with the arm .75 oi alever pivoted to the baelr oi the casing at the point 77. rlhe other armZ8 ot lever is in operative engagement with a slide bar 79, the end otthe lever arm 78 having' b ing' against a 'flange 80 on the side ot bar.The slide bar (9 is arranged in the head of the casing just inside theton edge plate ld thereof and is movable between this plate and thefixed portion 15 ot the coin chute. The slide bar 79 has in it a slot8l. Then the parts are occupying the initial position just referred tothe bar 79 will then be positioned Where the slot 81 in it will be inexact alignment with the slot 24 in the head ot the casing; therebypermitting ot the insertion of a coin. As the bolt is retracted onturning' the knob 46 the retraction of. the piece t5 will through theerossbar Z5 on the under side ther-sotl bear against the lever arm 7Gand thereby turn the lever and it, through the flange 80, Will ope ateto throw the slide bar 79 in a Aforward direction into a positionsubstantially as shown in Fig'. 2 Where the slide bar is operating toclose the slot 241 in the casing and prevent the insertion of a Coinuntil the. slide bar has been returned to its initial position. rlhereturn of the slide bar is obtained when the slide lmember 30 isretracted for retracting' the bolt on turning' the knob 56. luring suob`ope 'ation the head 29 of the sliding' member BO will engage the flange8O on the slide bar and thereupon return the slide bar to its initialrepresents a counter oil ordinary type. This coi4 iter is located insidethe easing;3 at a point adjacent the rear end ol' the slide bar 'I9 Thecounter is fined to the interior plate and lies between this plate andthe eover the fase ol? the counter showingr through slot 8# in thecover. The counter oper- ,d by an arm 85 which ef'tonds through ,ot 8din the plate 5. 'lhe end ot the n ies between the flange 80 of the slidebei' TS) .nd a flange 8T on this same Vidi-en liile bar moved forward'for closing); the slot :2st upon the retraction ot the bolt as aboveexplained the 'tlange 8'? Will contest with the Counter arm and therebyaetuate the counter. Upon the return ot the slide bar T9 to its initialposition the flange 8O thereon will engage the counter arm and return itto its initial operative position.

rlhe general operation oit the lock is as tollows: lt will tirst beassumed that the lool: is in plaoe secured to a door closing a room orapartment Controlled by the lock. A ooin is first inserted. The coinwill pass downwardly through the coin chute and come to rest upon theedges 39 and lill, respective y ot the members 30 and ',llhereupon uponturning the lrnob i6 the bolt will be moved into a retracted positionwhen the door may be opened. During,` the operation or retractJ ing thebolt by turning tne knob i6 the coin will be lifted into eontact .viththe piece Ll 'tor eiiieoting this operation. Siinultaneo'-'.sli,y withthe retraction or" the bolt the slide bar Z9 will be thrown torvvarijlclosing the coin slide 2e. At the same time the counter will beoperated. llt will now be assumed that the one turning' the knob 46 hasreleased his hold thereon and entered the apartment. Simultaneously withsuch release the bolt Will assume its normal extended or engaging'position and the door will become looked, the eoin then returning to itsinitial position contacting With the edges 39 and :lf-t as shown in l.rllhe slide bar '[9 @vill then be leit in its engaging' position closingthe eoin slot 2 4-, 'lhe one inside the apartment will then apply thelatch by turning` the thumb piece 60 which operates to prevent the boltbeing retracted by turning the exterior knob t6 and also its retractionby turningl the interior knob DuringY this period the coin slot remainsclosed, the previously inserted ooiu still remaining unreleased. lt willnew be assuund that the one inside the apartment desires to open thedoor. Vlhis plislied by turning' the knob 56 'for retract ing' the holt.ln order to turn the knob however. the reh so ot the latch must beellected by turning baolr the thumb piece 6()7 tor as previously'explained both the liixl knobs 46 and 56 are locked against turning bymeans ot' the latch. It the latch only controlled the turning of theouter knob i5 then one inside the apartment might forget the latch andopen the door by turning the interior knob 56 when the door could not beopened from the outside upon the insertion of another coin inasmuch asthe knob 4:6 would still be held against turning by the latch. Inasmuchas the latch locks both knobs against turning, the diiiiculty referrerto is obviated. Assuming now that the latch has been released then theone inside the apartment may open the door by turning the knob 56 whicheffects a retraction of the bolt. Simultaneously with such retractionthe coin is released to :tall into the bottom of the casing. At the sametime the slide bar 79 will be returned to its initial position leavingopen the slot 24 for the insertion oi another coin and the arm of thecounter will` be repositioned for the next operation. In other words,all the part-s will then assume their initial positions, the bolt beingextended and the door locked.

In case it becomes necessary to get into the apartment when the latch ison, the bolt can be retracted for opening the door through thekey-controlled lock 19.

Coins deposited in the bottom oit the casing are removable through ahinged door 88. This door is held closed by a key-controlled lock 89preferably of the pin type, the barrel 90 of the lock being providedwith an arm 91 which engages the bottom edge 92 of the cover and fromwhich it may be released on turning the barrel by the lock.
